Given numbers are 819, 228, 84, 668

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(819, 228) = 62244

GCD(819, 228) = ( 819 x 228 ) / 62244

= 819 / 228

= 819

Step2:

LCM(3, 84) = 84

GCD(3, 84) = ( 3 x 84 ) / 84

= 3 / 84

= 3

Step3:

LCM(3, 668) = 2004

GCD(3, 668) = ( 3 x 668 ) / 2004

= 3 / 668

= 3

So, Greatest Common Divisor of 819, 228, 84, 668 is 1
